After giving up gin, horrible indigestion issues (8)

I believe the answer is:

editions

I'm a little stuck... Click here to teach me more about this clue!

'issues' is the definition.
(edition is a kind of issue)

I don't understand how the rest of the clue works.

Can you help me to learn more?

(Other definitions for editions that I've seen before include "Copies of book about sedition" , "Repros" , "written publications?" , "issues for the press" , "Book published at different times" .)

I've seen this clue in The Hindu.
